Some users want to put the camera inside the house and position it to face outside to prevent the camera from being stolen easily. This article can help you recognize your cameras if they can be installed behind a window/glass.
The outdoor security battery cameras can not be installed behind a window/glass if you want to use the "Motion Detection" feature.
When the camera is behind glass or a window, it cannot detect motion outside the glass. Because the battery camera detects the motion of the object through the passive infrared sensor (PIR), and the PIR works by detecting the infrared radiation (radiant heat) emitted or reflected by the object, and the infrared radiation can not pass through the glass, so the motion behind the glass Detection will be unreliable. Therefore, the "Motion Detection feature" does not work reliably.
The outdoor security battery cameras are meant to be used outdoors and they are weatherproof for that purpose. If you want the camera to detect motions outside, we recommend that you place your outdoor camera outside.
For plug-in/wired indoor pan-tilt cameras, the answer is yes, as they use camera video analytics rather than PIR sensors to detect motions. As long as they "see", they can detect motions. So you can mount the camera behind a window/glass with confidence.
Even though the plug-in/wired indoor pan-tilt cameras can be installed behind a window/glass, please note that the reflection of the window/glass still would affect motion detection, resulting in many videos being recorded because the reflection was seen by the camera.
If you still have other concerns about this, please contact technical support. Provide us with the serial number of your camera you have for checking.
